Napawadee's place is great! We originally booked it for 4 nights, and decided to extend our stay, which was very easy to do thanks to Napawadee's flexibility and responsiveness. It is very centrally located and although it is a busy area, it is tucked away in a small alley which gives you peace and quiet. It might be a little bit difficult to find at first (it is located behind the Bangkok British School) but check-in and everything else goes very smoothly. The double bed was comfortable, the AC worked perfectly, everything is clean (the cleaning lady is very sweet!) and we enjoyed hanging out in the common space. I would definitely recommend this place!
